Time activity budget analyses of non-breeding mallards (Anas platyrhynchos) at Sultan Marshes, Sarp lake, Turkey was conducted from September to November, 1991. This study investigated the importance of Sarp lake with reference to non-breeding mallards. Feeding activity increased with cooler weather. The month of September showed maximum preening activity (33.3%). Preening is positively correlated with temperature (r=0.974, P<0.05). Temperature also has pronounced effect on agonistic activities (bill threats, chasing, biting etc.) (r=0.901, P<0.05). Locomotion, resting and alert activities showed no significant change. No courting activity was observed during the study period. Correlation among various activities was also observed. The overall study reveals the fact that Sarp lake is preliminary feeding ground for mallards and any change in the ecosystem leading to disturbance will results in displacement of waterfowl from the area.

Autumn migration dynamicsi body mass, fatload and stopover behaviour of wşllow warbler (phylloscopus trochilus linnaeus 1758) at Manyas Kuşcenneti National Park (Northwestern Turkey) Keşapli Didrickson, Özgür; Bilgin, Cemal Can; Department of Biology (2007) Turkey lies on one of major migratory routes between Palearctic and Afrotropical regions.Despite its importance for many species, few studies exist on bird migration over Turkey. In this study, autumn migration dynamics and stopover behaviour of Willow Warbler (Phylloscopus trochilus), a small insectivorous passerine, was documented and analyzed at Manyas Kuşcenneti National Park (northwestern Turkey). Birds were mistnetted, ringed, measured, weighed and fat-scored from mid August in 2002 and end of August ...
Hydropower production without sacrificing environment: a case study of Ilisu Dam and Hasankeyf Yalcin, Emrah; Tiğrek, Şahnaz (2016-01-01) The Ilisu Dam and HEPP Project, on the Tigris River in the South-Eastern Anatolia Region of Turkey, has been under debate for more than half a century due to its possible adverse effects on the environment. In particular, the proposed inundation of the archaeological sites around Hasankeyf has prompted strong criticism from national and international organizations. The primary reason for the administration's insistence on construction of the dam is its energy production capacity. The present study is an ass...
Water-Food Nexus in Sakarya Watershed Özel, Beyza; Başkan, Oğuz; Alp, Emre (null; 2019-06-19) Sakarya River is the Turkey’s third longest river and the Sakarya watershed covers 8% of the surface area of Turkey. Significant agricultural activities accounts for most of the water withdrawals in the upper Sakarya Watershed. Within the scope of water-food nexus, water efficiency of agricultural irrigation have to be improved to aid sustainable water and agricultural management in the study area. The water potential and water uses were evaluated by Water Evaluation Planning System (WEAP) model in Upper Sa...
Evaluation of the best management practices to control agricultural diffuse pollution in lake mogan watershed with swat model Özcan, Zeynep; Alp, Emre; Kentel Erdoğan, Elçin; Department of Environmental Engineering (2016) Lake Mogan which is located in Gölbaşı County, Ankara, Turkey is one of the most important wetlands of Turkey and it was declared as Special Environmental Protection Region in 1990. Total area of semi-arid Lake Mogan watershed is 970 km2 and dry farming is practiced approximately in 40% of the basin. Therefore, agricultural diffuse source pollution is a serious concern in the watershed. In the context of this thesis, the effects of implementation of different agricultural best management practices on sedime...
Modelling and forecasting snowmelt runoff process using the HBV model in the eastern part of Turkey ŞORMAN, ALİ ARDA; ŞENSOY ŞORMAN, AYNUR; Tekeli, A. E.; Sorman, A. Ue.; Akyürek, Sevda Zuhal (Wiley, 2009-03-30) Snowmelt runoff in the mountainous eastern part of Turkey is of great importance as it constitutes 60-70% in volume of the total yearly runoff during spring and early summer months. Therefore, determining the amount and timing of snowmelt runoff especially in the Euphrates basin, where large clams are located, is ail important tusk in order to use the water resources of the country in an optimal manner.
